[0034] A take-up unit 7 is arranged on one side of the wire unit 6, and the take-up unit 7 is arranged away from the upward drawing unit.

[0035] Specifically, the melting furnace 1 is used for melting copper materials, and the melted copper materials will flow and gather in the melting furnace 1. The upward drawing unit above the melting furnace 1 draws the melted copper materials into the crystallization part through the traction of the traction part 4, and then cools and forms rods in the crystallization part. The flow guide part in the crystallization part guides the cooling medium in the crystallization part, and the flow guide part can revolve around the inner part of the crystallization part while rotating itself. The formed oxygen-free copper rod is moved outward by the traction of the wire unit 6, and then is wound by the take-up unit 7.

[0036] It can be understood that first, the melting furnace 1 enables the copper material to be fully melted and uniformly flowed, providing a stable copper liquid source for the subsequent upward drawing process. The side wall of the melting furnace 1 is provided with an upward drawing port 2, so that the copper liquid can smoothly enter the upward drawing unit, not only improving the flowability of the copper liquid, but also avoiding large-scale heat loss, ensuring the high quality of the copper liquid. The upward drawing unit draws the melted copper liquid to the crystallization part through the traction of the traction part 4, realizes efficient transfer of the copper liquid, avoids the possible oxidation and pollution of the copper liquid in the traditional process, and ensures the high purity of the oxygen-free copper rod. The crystallization part as the core part of the upward drawing unit, the flow guide part inside the crystallization part realizes efficient flow guiding of the cooling medium through the double motion mode of revolution and rotation, so that the cooling medium forms uniform and dynamic flow in the crystallization part, thereby improving the cooling efficiency and heat exchange effect.

In addition, the dynamic adjustment capability of the flow guide part enables the cooling intensity to be adjusted in real time according to the temperature change in the crystallization process, further optimizing the crystallization quality, while reducing the consumption and energy consumption of the cooling medium, achieving the production goal of energy saving and environmental protection.

The formed oxygen-free copper rod is then smoothly and continuously moved outward by the traction action of the wire unit 6, avoiding the possible problems of rod breakage and deformation in the traditional process, ensuring the consistency and stability of the product. The side-by-side arrangement of the wire unit 6 further improves the production efficiency and shortens the production cycle. In addition, the design of the wire unit 6 also considers the safety and convenience in the production process, so that the operator can more conveniently monitor and adjust. The take-up unit 7 is located on one side of the wire unit 6, and its main function is to efficiently wind the formed oxygen-free copper rod, providing convenience for subsequent storage, transportation and processing. The design of the take-up unit 7 enables it to adapt to the winding needs of copper rods of different specifications and lengths, while ensuring the stability and consistency of the winding process. Through the efficient operation of the take-up unit 7, the formed oxygen-free copper rod can be neatly wound on the take-up reel, avoiding the possible disorder and damage in the traditional winding method, further improving the quality and market competitiveness of the product.

The production efficiency and quality of oxygen-free copper rods are improved, and the energy-saving and environmentally friendly production goal is achieved. First, the crystallization pipe 304 and the cooling liquid cavity 307 in the crystallization tank enable the cooling liquid to flow uniformly and efficiently, thereby achieving precise control of the entire crystallization process, not only improving cooling efficiency, but also avoiding internal defects of the copper rod such as cracks and pores caused by uneven cooling, thereby improving the mechanical properties and electrical conductivity of the copper rod.

[0045] It can be understood that first, the driving device includes the variable frequency motor 302 and the bearing 303, the bearing 303 is sleeved on the crystallization tube 304 and penetrates through the tank cover 311, and the variable frequency motor 302 drives the bearing 303 to rotate, and then drives the transmission device 5 of the flow guide part to move.

[0046] In some embodiments of the present application, referring to Figures 4-5 As shown in the figure, the transmission device 5 includes an internal meshing planetary transmission mechanism 501 and a planetary gear train transmission mechanism 503.

[0047] Specifically, the internal meshing planetary transmission mechanism 501 and the planetary gear train transmission mechanism 503 are matched for rotation by the bearing 303, the bearing 303 is driven to rotate by the variable frequency motor 302 through the belt, the bearing 303 is fixed on the crystallization tube 304, at this time the bearing 303 rotates without affecting the crystallization tube 304, when the bearing 303 rotates, it drives the internal meshing planetary transmission mechanism 501 and the planetary gear train transmission mechanism 503 to realize revolution and rotation at the same time, the bearing 303 extends through the planetary gear train transmission mechanism 503 to above the tank cover 311, and then is driven to rotate by the variable frequency motor 302.

[0048] It can be understood that through the internal meshing planetary transmission mechanism 501 and the planetary gear train transmission mechanism 503 of the transmission device 5, the motion efficiency and stability of the flow guide part in the oxygen-free copper rod production process are improved. First, the internal meshing planetary transmission mechanism 501 enables the transmission device 5 to realize high torque and high speed transmission in a compact space, thereby ensuring that the revolution and rotation of the flow guide part around the crystallization tube 304 are more stable and efficient. The planetary gear train transmission mechanism 503 further enhances the uniformity and stability of transmission through the cooperative work of multiple planetary gears 503a, avoiding the vibration and energy loss problems that may occur in traditional single-stage transmission, thereby improving the motion accuracy and cooling efficiency of the flow guide part. This double transmission mechanism not only optimizes the motion performance of the flow guide part, but also reduces the energy consumption of the driving device. In addition, the efficient cooperation of the internal meshing planetary transmission mechanism 501 and the planetary gear train transmission mechanism 503 enables the transmission device 5 to flexibly adjust the rotation speed and motion trajectory of the flow guide part according to production needs, thereby realizing dynamic control of the cooling intensity and crystallization speed, further optimizing the crystallization quality. The oxygen-free copper rod production process is efficient, stable and energy-saving. The core of the internal meshing planetary transmission mechanism 501 lies in its unique gear meshing method, which realizes efficient power transmission and motion control through the precise cooperation of the internal gear and the planetary gear.

[0049] In some embodiments of the present application, the planetary gear train transmission mechanism 503 includes planetary gears 503a, a sun gear 503b, a gear train ring 503c, and a second planetary carrier 503d, the planetary gears 503a are meshed with the surface of the sun gear 503b and the inner wall of the gear train ring 503c, the planetary gears 503a can be provided in multiple numbers, the planetary gears 503a are fixedly connected to the top end of the flow guide rod 8, the sun gear 503b is fixedly connected to the bearing 303 and rotates with the bearing 303, the gear train ring 503c is fixedly connected to the inner wall of the tank body 310, the second planetary carrier 503d is connected to the inside of the bearing 303, and the second planetary carrier 503d is connected to the top of the rotary cutter.

The planetary gear 503a is located at the top of the flow guide rod 8, thereby driving the flow guide rod 8 to rotate. Since the sun gear 503b and the planetary gear 503a outer ring are also provided with a gear train ring gear 503c, when the bearing 303 drives the sun gear 503b to rotate, the flow guide rod 8 can rotate around the planetary gear 503a while rotating.

[0051] It can be understood that the planetary gear train transmission mechanism 503 is composed of the planetary gear 503a, the sun gear 503b, the gear train ring gear 503c and the second planetary carrier 503d. The core is to realize the revolution and rotation movement of the flow guide part through the mutual meshing of the planetary gear 503a, the sun gear 503b and the gear train ring gear 503c. When the bearing 303 rotates, the sun gear 503b fixed on the bearing 303 rotates, the sun gear 503b meshes with the planetary gear 503a and drives the planetary gear 503a to rotate, and the planetary gear 503a fixed at the top of the flow guide rod 8 drives the flow guide rod 8 to move. Since the planetary gear 503a meshes with the inner wall of the gear train ring gear 503c, the flow guide rod 8 not only revolves around the crystallization tube 304, but also rotates under the drive of the planetary gear 503a. This double motion mode ensures the uniform flow of the cooling liquid in the crystallization tank, avoids the internal defects of the copper rod caused by uneven cooling in the traditional process, such as cracks, pores, etc., thereby improving the mechanical properties and electrical properties of the copper rod. In addition, the planetary gear train transmission mechanism 503 makes the movement of the flow guide part more stable and efficient, reduces vibration and energy loss, and further optimizes the cooling efficiency and crystallization quality. Through the planetary gear train transmission mechanism 503, the production process of oxygen-free copper rod is efficient, stable and energy-saving. The fixed connection of the planetary gear 503a and the meshing with the gear train ring gear 503c ensure that the flow guide part always maintains a stable movement state during revolution and rotation, avoiding the vibration and noise problems that may occur during high-speed operation of the traditional transmission device 5, thereby prolonging the service life of the equipment, reducing maintenance cost and downtime. The sun gear 503b, the planetary gear 503a and the gear train ring gear 503c work together to not only realize efficient movement of the flow guide part, but also further optimize the flow and heat exchange efficiency of the cooling liquid by dynamically adjusting the movement trajectory and speed.

[0054] It can be understood that the internal meshing planetary transmission mechanism 501 is composed of the first pinion 501a, the ring gear 501b and the first planetary carrier 501c, and the core is to realize the stable movement of the flow guide part through the meshing of the first pinion 501a and the inner wall of the ring gear 501b. When the planetary gear train transmission mechanism 503 is driven to rotate by the variable frequency motor 302, the internal meshing planetary transmission mechanism 501 rotates synchronously, wherein the first planetary carrier 501c is connected to the bearing 303 on the inner side and connected to the top of the flow guide rod 8 on the outer side, ensuring that the flow guide rod 8 always remains stable during movement. The precise meshing of the first pinion 501a and the ring gear 501b not only realizes the efficient movement of the flow guide rod 8, but also ensures the stability and uniformity of the crystallization process by preventing the displacement of the crystallization tube 304. Avoiding the internal defects of the copper rod such as cracks and pores caused by the displacement of the crystallization tube 304 in the traditional process, thereby improving the mechanical properties and electrical properties of the copper rod.

The core is to drive the traction device 401 through the traction motor 402 to realize efficient traction of the copper rod. The position design of the traction device 401 ensures the smooth movement of the copper rod in the crystallization tube 304, avoiding the internal defects of the copper rod such as cracks and pores caused by uneven traction in the traditional process, thereby improving the mechanical properties and electrical conductivity of the copper rod.

[0057] In some embodiments of the present application, the take-up unit 7 includes a take-up column 701 and a take-up wheel 702. The take-up column 701 is provided with several take-up wheels 702 at the upper end of the several take-up columns 701.

[0058] It can be understood that the take-up unit 7 improves the maintainability and scalability of the equipment. The take-up column 701 and the take-up wheel 702 make equipment maintenance and replacement more convenient, reducing equipment downtime and improving production line efficiency. Secondly, the take-up unit 7 improves the take-up quality and consistency of the copper rod. Through the control system, the movement of the take-up wheel 702 can be adjusted to ensure that the tension, speed and uniformity of the copper rod during the take-up process are optimal. Not only can it avoid problems such as deformation, uneven winding or broken wire during the take-up process, but also it can improve the final quality of the copper rod.

[0059] One of the above embodiments is used for the production device of the upward drawing method oxygen-free copper rod. By setting a flow guide part in the crystallization part, the flow guide part revolves around the crystallization part while rotating itself under the drive, which can optimize the flow path and distribution efficiency of the cooling medium. The revolution makes the cooling medium form a uniform flow cover around the crystallization tube, avoiding local uneven cooling. The rotation further enhances the turbulent effect of the cooling medium, improving the heat exchange efficiency. This double motion mode allows the oxygen-free copper rod in the crystallization tube to be cooled more uniformly and quickly, thereby improving the crystallization efficiency and microstructure density of the copper rod. At the same time, the optimized flow guide of the flow guide part to the cooling medium also reduces the amount and energy consumption of the cooling medium, reducing resource waste in the production process. In addition, this design can also reduce defects such as cracks and pores that may occur during the crystallization process of the copper rod, further improving the mechanical properties and electrical conductivity of the oxygen-free copper rod.
